2 Claims. (Cl. 18972) This invention relates to a new and useful windowconstruction and particularly to a resilient window sash suspensionincluding novel weather stripping means.

The invention includes a plurality of sash supporting members which maybe tted or secured to a window opening in a given structure. Thesupporting members include means whereby window sashes may beresiliently suspended therein. Also the various components are formed tot snugly to provide a substantially weather tight unit when assembled.

A particular object and feature of this invention is the provision ofweather stripping formed integral with one sash and disposed between thehorizontally spaced sashes whereby the closed windows are weather tightat the point of juncture.

Another object of the invention is to form the top and bottom sashsupporting members to receive the sashes in a snug and weather tightmanner and to provide eiective weather stripping at the top and at thebottom of the installation of windows.

Also, an object of this invention is lche provision of supportingmembers which may optionally be secured permanently at a window openingor which may be removably fitted therein. If removably fitted therein anumber of advantages will suggest themselves, as for example, the entireunit may be removed to facilitate painting of the surrounding structure.

A further object resides in the resilient suspension of the sashes inthe supporting members. The resilient suspension renders the sasheseasily removable when desired, as when painting the surroundingstructure, or to permit maximum ventilation. Also, minor variations insizes of the sashes relative to the window opening are compensated bythe resilient suspension as are seasonal variations in sizes of windowopenings resulting from alternately damp and dry conditions.

The invention is particularly adaptable to and apprehends metalconstruction. The. use of non-corroding metals renders paintingunnecessary, and the window frames may outlast the life of thesupporting building structure. Additionally, the various members areindividually secured or fitted in the window openings. Thus they mayeasily be cut to t a window opening of a given size, facilitatinginstallation.

These, and other objects of this invention will become apparent from anunderstanding `of the following written description as illustrated inthe accompanying drawings wherein Fig. 1 is a plan view of the installedwindow construction, partially broken away, viewing the Window from theinterior of the building;

Fig. 2 is a fragmentary sectional perspective view, partly broken awayto illustrate the juncture of the sashes;

Fig. 3 is a broken, sectional side elevation;

Fig. 4 is a fragmentary sectional view taken substantially on line 4-4of Fig. 1; and

ICC

Fig. 5 is an exploded fragmentary perspective view of details of theinvention.

The window comprises a pair of rectangular, vertically slidable sasheswhich may be referred to as top sash 2 and bottom sash 3, as they appearin Fig. 1. The said sashes are substantially identical in structure,with one exception, as hereinafter noted. Each sash may be provided witha rectangular pane 5 having on each edge a channel-shaped, metallic,protective strip, the protective strips of the top and bottom sashesbeing designated respectively as 2a and 3a. One flange 4 of each stripis shorter than the other flange 6. A wooden strip 7 is disposed in thebottom of the channels between the anges, substantially ilush with theinner edge of said shorter flange 4. The flanges 4 and 6 are spaced fromeach other a distance substantially equal to the thickness of standardWindow panes. The pane-receiving members 2a are jointed as bestillustrated in Fig. 5 and are secured to each other at their corners, asby rivets 10a passing through the strips 2a and 3a and the enclosedwooden strip 7, to form the top sash 2, and with the short anges 4unilateral and the long flanges 6 unilateral. The pane-receiving members3a are similarly secured together to form the bottom sash 3. The windowpane 5 is secured in each sash by the segment of the long flange 6protruding above the wooden strip 7 and being secured on the other sideby glaziers points (not illustrated) inserted in the wooden strips and asuitable glazing compound 15.

The upper member of each sash is provided with knobs 8 to facilitateVertical adjustment of the sashes. The said knobs 8 are horizontallyslidably mounted and project outwardly through enlarged slots 8a on theinterior side of the top sash members. The knobs 8 are secured to springbiassed latch members, not illustrated. The latches releasably engagespaced apertures (not illustrated) in the jambs 9. For construction andoperation of the said latch members reference is made to my Patent2,288,936.

A pair of jambs 9 each dene in cross section a shallow channel,centrally divided by a ridge or parting strip 10. The distances betweeneach leg 9a and the parting strip of the jamb is substantially equal tothe cross sectional thickness of a sash and such that each jamb 9defines a pair of guides 11 and 12 slidably receiving a sash on eitherside of the parting strip 10. The guides will be referred torespectively as top and bottom sash receiving guides 11 and 12.

A pair of horizontally opposed, relatively deep channels 13 each havinga cross sectional width substantially equal to that of the jambs 9 toslidably receive the jambs 9. A plurality of helical compression springs14 are secured at spaced intervals to the interior surface of the web13a of each channel 13, and resiliently bias jambs 9 outwardly towardsnug engagement with sashes 2 and 3, but facilitate sliding of thesashes.

Again referring to the sashes 2 and 3, the lower member 2A of the topsash 2 (as in Figs. 1 and 2) is deformed adjacent the top of its longerflange 6 to define a V-shaped lprotuberance 16. The said protuberance 16extends substantially the length of said lower sash member Zapof the topsash 2. The apex 16a of the V-shaped protuberance 16 extendshorizontally from the lower sash member 2A a vdistance substantiallyequal to the cross sectional dimensions of the parting strip 10 of thejambs 9.

A top and bottom weather strip 17 and 18 are each longitudinallydeformed to define in cross section an S including a fourth orreinforcing leg 19 which is folded back parallel and in close proximityto the adjacent leg of the S shaped strip. This cross sectionalformation, il-

lustrated in Figs. 3 and 5, provides a snug, sash receiving recess 21.`The cross, sectional width of each said weather The members may beeasily cut with a metal saw.

They should be cut to approximately the following lengths; the channels`13 and jambs 9 shouldbe substantially the Asame lengths as thewindowopening; theweather strips 1.7 and 18 should be shorter than the width.of the-windowsopeningfby substantially twice the deptlrof the channels;the sashes'Z and"3..should be slightly wider than the weather strips.and approximately one half the heightof theiwindowopening. Theresilientinstallation will.compensate for minor .variations in size of sashesrelative to the window opening.

The nchannels 13 are ,verticaly secured in the frame Wallto open towardeachother. They may berigidly secured in place, as Iby screws or nailsdriven through web 13a, or they may be removably secured between stripsof spaced molding.

A jamb 9 is then temporarily manually biassed against the compressionspringsand within a channel.

The bottom Yweather st-rip 18 is inserted 4at the bottom of the windowopening between the jambs '9 abutting the 4bottoms of the latter. Thesaid bottom weather strip 18 is positioned with its reinforcing leg 19interior relativeto the rest of the weather strip 18 and with itssashreceiv-ing recess Zlopening upwardly and in vertical alignment withthe `bottom sash or guides 11. The top Weather strip is oppositelydisposed between the tops of the jambs 9, i. e., fsuch that itsreinforcing leg 19 is exterior relative to the rest of the top weatherstrip 17 and with its sash receiving recess 21 opening downwardly andaligned with the top sash guides 12.

Similar tothe channels 13, the weather strips may be secured in position'by nails or screws. Or they may be removablyfdisposed between spacedstrips of molding.

The jambs 9 are now secured in position being biassed between theweather strips 17 and 18 on one side and the compression springs 14 onthe other.

The sashesmay now be secured in place.

Assuming the window is being installed from the inside of the building,the top sash 2 is preferably inserted first. One edge of the top sash isfitted into a topisash guide 12 of one of the jambs 9 with the Vprotuberance '.16 at the bottom of the sash and toward the worker. Thesash is forced against the top sash guide in which it is fitted, forcingthe jamb outwardly and so the other side of the sash may clear theinterior guide 11 and Vthe parting strip 10 of the other jamb to iitinto the top sash guide of the other jamb.

The bottom sash is similarly installed in the interior guides 11 of thejambs.

The-sashes may-now-bemoved vertically in their respective guides. 4Whenclosed, that is, when the top sash 2 is moved as `far as it will gointothe sash receiving recess `21 of. the top weather strip 17, .and Vthebottom sash `3 ismoved as far asit will go into the bottom weath` erstrip 18, the V protuberance 16 spans the distance between thehorizontally spaced sashes, providing a substantially weather tightjuncture. The Vsash receiving recess 21 of thetop and'bottom weatherstrips ksimilarly render the unit weather tight at'the top andbottom, as'dothe sashes'fitted in the guides at the sides of the unit.

The top and bottom sashes may be lowered or raised for ventilation. 'if-fmaximum ventilation is desired the sashes may easily be removed bypressing each sash` they may easily be removed to facilitate painting ofthe `surrounding structure.

Although the foregoing invention has been described in some detail byway of illustration and example for purposes of clarity ofunderstanding, it is understood that certain changes and modificationsmay be practiced within the spirit of the invention and scope of theappended claims.
